What is the function of glucosamine in cartilage?

The function of glucosamine in cartilage is to stimulate the formation and repair of cartilage. Glucosamine is a chemical found naturally in the body, in the fluid that cushions joints. When taken in supplement form, glucosamine has been found in some studies to reduce the pain experienced by some people who have osteoarthritis. Studies are also exploring whether glucosamine supplements could restore the cartilage in arthritic joints or slow the progression of arthritis. But there is no good evidence yet that glucosamine supplements can provide these benefits. Talk to your doctor before taking glucosamine or any dietary supplement.
